Materials

Match the film
to the tray.

The seal is a system: film, substrate, heat, pressure, and dwell. Tell us what you fill and we will recommend the film and sealing window.

  • Haze ≤8%; anti-fog performance 48h+ at 0–4°C
  • Common widths: 260, 280, 310, 380, 430, 450, 540 mm

How to specify

Four questions.
One correct lid.

Most sealing problems start with an incomplete spec. Send these four answers and we can quote and sample faster.

01

What is the tray material?

PP, PE, PET, PS, PVC, ABS, aluminum, or paper. The resin decides the film chemistry.

02

What is the shape and size?

Cup diameter, tray dimensions, corner radius, and flange width. A drawing or sample is ideal.

03

Peel or high-strength?

Easy peel, clean peel, or a permanent seal. This changes the film structure and seal window.

04

How is it filled?

Hot fill, cold fill, retort, or modified atmosphere. Temperature and pressure affect the seal.

Send a tray and a lid. We'll match the seal.

Share your substrate, dimensions, filling process, and target peel. We will confirm the film, MOQ, and lead time — and send a sample for your sealing trial.

Ask on WhatsApp

Standard sealing film starts from 100 kg. A first trial can be arranged; the exact MOQ depends on format and print.

Yes. We print logos, patterns, and text on roll stock and die-cut lids, with easy-peel or strong-seal options. Artwork proof is approved before production.

Usually temperature, time, pressure, or lid alignment. Check the sealing parameters, make sure the lid is flat, and confirm the film matches the tray. Our Skyvac anti-fog film is designed to stay flat under refrigeration.

Common causes: insufficient temperature or pressure, contamination on the rim, a lid that is too small, or a pinhole in the film. Clean the rim, adjust the sealing window, and test with a vacuum leak check.

Yes. High heat or a thick adhesive layer can make peeling difficult. We can supply an easy-peel structure and adjust the seal window for a cleaner open.

Our anti-fog sealing film targets haze ≤8% and can keep the lid clear for 48h+ at 0–4°C. Performance depends on the food, pack atmosphere, and storage; we will send a sample for your test.

No. Once the aluminum lid is peeled, the sealing layer is destroyed and the seal cannot be reused.

Send a tray and lid sample, or run a seal test and vacuum leak check. We supply PP, PE, PVC, PET, PS, ABS, aluminum, paper, and glass-container films, in easy-peel and strong-seal versions.
